Abu Kathir narrates from his father that: I asked Abu Dharr (raadi Allaahu ‘anhu), “Show me an action which if the slave does it he will enter al-Jannah.” He said, “I asked the Messenger of Allah (ﷺ) about that and he said, ‘That he has eemaan in Allah.'” So I said, “O Messenger of Allah! Isn’t there action along with the eemaan? He said, “Let him give a little of what with which Allah provides him.” I said, “What if he is destitute, not owning anything?” He said, “Let him say what is good with his tongue.” I said, “Then what if he is incapable and his tongue will not express what he intends?” He said, “Then let him help someone who has been overcome.” I said, “Then what if he himself is weak and has no power?” He said, “Then let him make something for a clumsy, unhandy person.” I said, “Then what if he himself is clumsy and unhandy?” Then he turned to me and said, “You don’t want to leave your friend with anything good, do you? Then let him protect people from his own mischief.” I said, “O Messenger of Allah! All of this is easy.” So he said, “By who One in Whose Hand is my soul! There is no slave who does any one of these practices, seeking thereby that which is with Allah, except that I will take him by his hand on Yawm al-Qiyaamah until he enters al-Jannah.”

[Saheeh ibn Hibbaan #373, and he declared it saheeh. Sheikh al-Albaani graded it as saheeh li-ghairi in al-Saheehah #2668. al-Haakim reported it with a different wording in Mustadrak al-Haakim #212, and he considered it saheeh according to the conditions of Muslim. Sheikh al-Albaani graded it as Saheeh li-ghairi in al-Saheehah #2668. Al-Tabarani also reported a different wording of the hadeeth in al-Kabeer, which al-Albaani graded as hasan li-ghairi.]

Ibn Rajab mentioned this narration in Jaam’i al-‘Uloom w’al-Hikam, after which he mentions:

A stipulation is this hadeeth is that all of these actions must have purity of intention, as is mentioned in [a previously mentioned] hadeeth of ‘Abdullah ibn ‘Amr discussing the forty characteristics. And this is like Allah’s saying, “There is no good in much of their private conversation, except for those who enjoin charity or that which is right or reconciliation between people. And whoever does that seeking the pleasure of Allah – then We are going to give him a great reward” [4:114].
